Single-use analysis bottle and color results matching system for colorimetric reagents

Abstract

Disclosed herein is a system for indicating via a colorimetric reaction the presence of a substance in a sample, comprising: a bottle containing a reagent and closable by a removable lid; and a label coupled to the bottle and comprising visual indicators for indicating the presence of a substance in a sample, wherein upon mixing the sample with the reagent in the bottle, the mixture changes to a particular color based on the identity of the substance in the sample, and each visual indicator is colored the color the mixture would be if a respective substance is in the sample, such that correspondence between the color of the mixture and the color of a visual indicator indicates the presence of the substance indicated by that visual indicator.

1 . A system for indicating via a colorimetric reaction the presence of a substance in a sample, comprising:
 a bottle containing a reagent and closable by a removable lid; and   a label coupled to the bottle and comprising visual indicators for indicating the presence of a substance in a sample,   wherein upon mixing the sample with the reagent in the bottle, the mixture changes to a particular color based on the identity of the substance in the sample, and each visual indicator is colored the color the mixture would be if a respective substance is in the sample, such that correspondence between the color of the mixture and the color of a visual indicator indicates the presence of the substance indicated by that indicator.   
     
     
         2 . The system of  claim 1 , wherein: the bottle is transparent; and at least a portion of the label is transparent such that the reaction within the bottle, and the color of the resulting mixture in the bottle, can be observed through the label. 
     
     
         3 . The system of  claim 1 , wherein each visual indicator comprises a colored panel. 
     
     
         4 . The system of  claim 1 , wherein the lid includes indicating means for indicating an amount of the sample to be mixed with the reagent. 
     
     
         5 . The system of  claim 4 , wherein the indicating means comprises a visual perimeter provided on an upper surface of the lid. 
     
     
         6 . The system of  claim 4 , wherein the indicating means comprises a well via which an amount of the sample can be measured out. 
     
     
         7 . The system of  claim 1 , further comprising a light source for illuminating the mixture and/or the label. 
     
     
         8 . The system of  claim 7 , wherein the light source is arranged to project light through a bottom and/or side of the bottle. 
     
     
         9 . The system of  claim 7 , wherein the light source comprises any one of: a torch; a flashlight; a laser; a lightbulb; a candle; or natural light. 
     
     
         10 . The system of  claim 1 , wherein the label is formed from plastic and is adhered to a sidewall of the bottle. 
     
     
         11 . A method of identifying a substance in a sample using the system of any one of the preceding claims, comprising:
 observing the color of the reagent;   removing the lid from the bottle;   adding the sample into the bottle;   closing the bottle with the lid;   mixing the sample with the reagent to form a mixture;   observing the color of the mixture after a predetermined period of time; and   comparing the color of the mixture with one or more colors of the visual indicators.   
     
     
         12 . The method of  claim 11 , wherein observing the color of the mixture includes observing the color of the mixture during the colorimetric reaction. 
     
     
         13 . The method of  claim 11 , wherein the step of adding the sample into the bottle comprises measuring out the amount of the sample based on the indicating means. 
     
     
         14 . The method of  claim 11 , wherein if the color of the mixture does not correspond with the colors of any of the visual indicators, the method further comprises comparing the color of the mixture with colored visual indicators provided on a separate test result chart.
